Here is a comprehensive summary of the Wikipedia article on AT&T Stadium:

AT&T Stadium, nicknamed "Jerry World" after Dallas Cowboys owner Jerry Jones, is a retractable-roof stadium in Arlington, Texas, that opened in 2009 as the home of the NFL's Dallas Cowboys. Built at a staggering cost of $1.15 billion—making it one of the most expensive sports venues ever constructed—the stadium was funded through a mix of city taxes, NFL loans, and private investment. It holds the NFL record for regular-season attendance with 105,121 fans, and its seating capacity can be reconfigured to exceed 100,000, making it the largest stadium in the league. The facility's design features two nearly 300-foot-tall arches, a massive center-hung video board (the largest HDTV screen in the world at its installation), and glass end-zone doors, all envisioned by lead architect Bryan Trubey to function as a civic structure. Beyond hosting Cowboys games, it is the venue for the Cotton Bowl Classic, the Big 12 Championship Game, and was one of 11 US venues selected to host matches during the 2026 FIFA World Cup, alongside concerts, rodeos, and other major events.
